That doesn't sound too much different than just ditching my current profile and creating a new one, to be honest. What exactly could I expect to lose in the process of doing that as far as my settings go? At this point I'm seriously considering just backing up my bookmarks, and starting completely fresh. And if that doesn't work... hello SeaMonkey or Chrome/Chromium. Can't try the new Opera, because it's not available on Linux yet (as usual...).

I'm really getting tired of playing these stupid games with Mozilla. It's getting ridiculous.

The link goes into detail on what you'd lose and what's saved, but for most users the big bite will be having to reinstall add-ons, reopen your windows/tabs (login/cookie info/history are kept intact though) and re-add more advanced things like custom search engines, mime settings, and custom toolbars/user styles.

If that worked, then it's worth trying a profile reset since it's far less intense than a completely new profile (you can delete the test one easily enough). I'd only start from scratch if the new profile worked, but resetting your current one didn't. Of course I always advocate backing up your profile before tinkering with it to reset it/etc.

I think I will just do that and hope it works well. Meanwhile I will back up my current profile, and possibly move it back over if there are problems. Thanks for the suggestions. I am not anticipating the "Firefoxication" or "De-Chromification" of my settings though... it it gets to be too much of a pain in the ass, I might have to give Firefox a goodbye.
